Load balancing method based on object storage device

Abstract

It's an object-based storage device load balancing method, belonging to the computer storage technology, aiming at balancing the distribution of the system load in the storage nodes by reasonable scheduling of I / O load and hot data migration, to take full advantage of high-performance of storage device nodes. The order of the invention includes: (a) active load detection steps; (2) equipment load statistics steps; (3) object migration and copies management steps; (4) object properties expansion steps; (5) I / O request processing steps. The invention expands the SCSI protocol standards of object storage devices (OSD). With the advantages of object storage model, it provides basis for I / O scheduling decision, makes full use of the computing capacity of all the storage nodes to balance the load, reduce storage system response time and increase the storage system throughput.

Description

technical field

[0001] The invention belongs to the technical field of computer storage, and in particular relates to a load balancing method based on an object storage device. Background technique

[0002] With the rapid development of computer technology and network communication technology, the amount of global information storage is increasing rapidly at a rate of more than 30% per year, and the growth rate of data stored on hard disks is as high as 114%. Faced with the explosive growth of data volume and people's demand for storage system capacity, security, scalability and availability, the traditional direct access storage mode (Direct Access Storage, DAS) has been unable to do what it wants, which makes network storage become a storage The inevitable trend in the field of technology. The main architectures of current network storage include network attached storage (NAS, Network Attached Storage) and storage area network (SAN, Storage Area Network). Although NAS an...
